D Correct answer
Explanation

 Transpiration creates negative pressure in adjacent subsidiary cells of the stomata, which get transferred down the xylem, which results in uptake of the water and nutrients from the soil which is ultimately utilised in the process of photosynthesis. Thus, its absence can affect overall functioning of plants.
